About me

Building things that work

I'm a software engineer with hands-on experience building backend services, RESTful APIs, and data pipelines. My work spans Python and Node.js ecosystems, relational and NoSQL databases, and cloud infrastructure on AWS.

I care about writing maintainable code, automating CI/CD pipelines, and containerizing workloads with Docker and Kubernetes. I've shipped projects across fintech, productivity tooling, and data processing domains.

Outside of work I practice DSA in Java, explore stock market data systems, and experiment with low-level topics like steganography and image processing.
